/**
 * Shuffles an array using mt_rand() instead of rand().
 * CAUTION: Unlike shuffle(), returns a new array, leaving the source untouched. It's better that way.
 * CAUTION: Won't work with associative arrays. Who would shuffle an associative array anyways?
 * 
 * @param array $deck The index-based array to be shuffled.
 * @return array A new array containing exactly the same elements in a random order.
